But in fact, wide distribution of average radius of pore throat which ane in reservoir make the changed drilling and completion fluid have good shield temporary blocking effect on only a few well .

在钻井过程中为了达到保护储层的目的,通常根据储层的平均孔喉半径,在上部钻井液中加入合适粒经的暂堵剂,再配合胶体填充粒子等,将上部钻井液改造为完井液;但往往在实际井中,储层孔喉半径分布范围较宽,导致经改造后的钻井完井液仅对某井段具有较好的屏蔽暂堵效果,而对另外的井段则不能起到较好的保护储层作用。

Only with clear knowledge of reservoir characteristics, potential damage factors, sensitivity and the damaging mechanisms of drilling and completion fluids, can compatible and reasonable drilling and completion fluid technology be worked out.

油气层保护技术有很强的针对性,只有弄清储层特征、潜在损害因素、敏感性和钻井完井液损害机理,才能提出与储层相匹配的、合理的保护油气层的钻井完井液技术措施。
